Javascript | .Net

I was recently very busy with a lot of work and did not have the chance to post on my blog. But during this period I came across a very powerful javascript library called jQuery. Its just fantastic. For the bulk of features it has you may expect a monster javascript library, but it is just 16kb (minified and gzipped). So thats hardly a 2 second overhead for end user. It eases DOM Traversal, Animations, events and AJAX. I came across this library almost 3 weeks back. And everytime I explored more features of this library, I am becoming more interested in this. I would rate this 10/10. What are you waiting for ? Checkout this cool library at jQuery. BTW did I mention it has plugin support and has a huge collection of plugins ? Checkout the plugins at Plugins.

Why didnt I come across JQuery early ?

Have you heard about Doloto ???

Have you heard about Doloto ???

Have you heard about Doloto ??? Well Doloto is an Code Splitting system from Microsoft Research labs. As of this writing it is not available publicly yet. But if you are interested you can read a pdf about it from here.

The goal of Doloto is to reduce the initial startup time for Web 2.0 applications. Well generally most Web 2.0 applications have all the Javascript in a single file and is sent to the browser. So the user has to wait till all the file gets downloaded, before he can start interacting with the application. Dial Up users would have experienced the frustration of seeing a ‘loading…’ for a long time, Doloto’s goal is remove that frustration.

If you take a look at this link, you can see that most of the websites hardly use 20 - 30% of the Js code when the page initially renders, so by cutting this initial payload to a minimum, these sites can be loaded much faster.

The idea of Doloto is to send only the initial payload and the rest can be transferred silently in background or on demand. Well yes it is a very interesting topic, dont forget to read the 25 page pdf at the Microsoft’s research site.

Links Referred:

1) Doloto: Code Splitting for Network-Bound Web 2.0 Applications

2) Split the Initial Payload

A Simple Way to detect spambots

A Simple Way to detect spambots

This is an old trick but worth being mentioned again:

now hide this textarea using javascript / css, by setting the display to none. Now when the form is submitted if you find any text here you can safely assume its a spambot.
